Factorial Analysis of Variance

** Please see the attached files for the complete problem description **

Please see attached problem with formulas. An experiment was designed to test the relative effectiveness of a computer-taught method of instruction compared with a conventional lecture method. Two samples of three subjects each were selected from among students of good aptitude and assigned to the two methods of instruction, as shown below
(please see the attached file)

Two samples of the same size were selected from among students of ordinary ability and assigned to the same methods of instruction. In the test trial, the 12 students earned the scores shown in the table above.
(a) Find df_total, df_R, df_C, df_WC, and df_RXC

(b) Find SS_total, SS_R, SS_C, SS_WC, and SS_RXC

(c) Calculate the several variance estimates appropriate to a two-way ANOVA, and present the results thus far developed in an analysis of variance table
